“…Among the earlier studies on mathematical formulation of stability analysis were examined by Harris et al (2009) Merkin (1986, Roşca and Pop (2013), and Weidman et al (2006). Many recent works also discussed the existence of dual solutions and emphasis on stability analysis (Bakar et al 2018;Dzulkifli et al 2018;Hamid & Nazar 2016;Jamaludin et al 2018;Kamal et al 2019;Naganthran et al 2018;Soid et al 2018). All the reported literatures implemented the bvp4c solver in the MATLAB software to examine the paired and stability solutions.…”

The present study accentuates the Marangoni convection flow and heat transfer characteristics of a hybrid Cu-Al 2 O 3 / water nanofluid past a stretching/shrinking sheet. The presence of surface tension due to an imposed temperature gradient at the wall surface induces the thermal Marangoni convection. A suitable transformation is employed to convert the boundary layer flow and energy equations into a nonlinear set of ordinary (similarity) differential equations. The bvp4c solver in MATLAB software is utilized to solve the transformed system. The change in velocity and temperature, as well as the Nusselt number with the accretion of the dimensionless Marangoni, nanoparticles volume fraction and suction parameters, are discussed and manifested in the graph forms. The presence of two solutions for both stretching and shrinking flow cases are noticeable with the imposition of wall mass suction parameter. The adoption of stability analysis proves that the first solution is the real solution. Meanwhile, the heat transfer rate significantly augments with an upsurge of the Cu volume fraction (shrinking flow case) and Marangoni parameter (stretching flow case). Both Marangoni and Cu volume fraction parameters also can decelerate the boundary layer separation process.
